What we fix on dishwashers
- Won’t drain: blocked drain pump, clogged filter, bad drain solenoid. This is one of the most common calls we take
- Dishes not clean: clogged spray arm, wash pump failure, water not hot enough
- Leaking: door gasket, worn pump seal, inlet valve
- Won’t start: door latch, control panel, thermal fuse
- Won’t fill: inlet valve, stuck float, water supply
- Loud running: wash arm bearing, chopper blade, drain pump
- Door won’t latch: latch assembly, hinge spring
- Error codes: E1, E4, F8, i30, and the rest, on every brand

Try these before you call
A short list worth running first:
- Power and latch. Confirm the door clicks fully shut and the breaker did not trip. A half-latched door is a common “won’t start” cause.
- Delay start. Some models default to a delay cycle after a power blip. Check the panel before you assume the machine is dead.
- Filter. Most machines built after 2010 have a twist-out filter at the bottom of the tub. A clogged one causes standing water and weak cleaning. Rinse it under the tap and reinstall.
- Drain hose. If the machine was moved recently, or someone worked under the sink, confirm the drain hose still has its high loop or air gap at the cabinet.
If none of that fixes it, stop. The rest means pulling the machine and testing parts.
What the actual repair takes
The failures above (worn pump seal, dead heating element, bad board, cracked sump) all live inside the machine. Diagnosing them right means metering components, tracing the code to the actual part, and ordering brand-specific parts. Bosch, LG, and Samsung in particular use their own connectors and calibration steps that are not in the general guides. Guess wrong and you get a worse failure or a flooded cabinet.
We test, diagnose, and repair in one visit when we have the part on hand, and we get people on the schedule fast, often same or next day.
